AQA GCSE Physics Energy Changes and Thermal Stores Worksheet

What is covered

Questions and skills covered

The worksheet contains 3 pages of printable questions. A separate 2-page solutions PDF makes it easy to mark, review or share answers after the activity.

• Energy changes in systems and thermal energy stores
• Specific heat capacity calculations using change in thermal energy
• Required practical data, repeat measurements and anomalous results
• Directional energy-transfer reasoning and complete energy accounts

About this activity

Thermal-store blocks provide the context for specific heat capacity calculations and the heated-block required practical. Later questions ask pupils to handle anomalous results, compare materials and explain the direction of a measurement error, rather than simply naming heat loss.

Before you start

Calculate a temperature change, convert between joules and kilojoules, and substitute into energy = mass x specific heat capacity x temperature change.
